Not sure what a bike fit is going to do for pain related to the IT band. You want to find the root cause and eliminate it. For me, I gave the IT band slack by loosening my TFL. I now include that exercise in my morning mobility exercises, and never have knee problems (due to the IT band). See this brief Kelly Starrett mwod video (I know enough to decipher it, but not sure if others will get much out of it): IT Band Hell | Feat. Kelly Starrett | Ep. 61 | MobilityWOD - YouTube
